[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 The utility model discloses a dual-channel nasal oxygen cannula, comprising a nasal oxygen cannula body 1, and also comprising:
[0023] The humidification mechanism 2 includes a humidification box 21 fixed to the end of the nasal oxygen tube body 1. The cover of the water inlet on the rear side of the humidification box 21 is opened, and then distilled water is added to the inside of the humidification box 21. After the addition is completed, the cover of the water inlet is tightened. Distilled water is stored in the humidification box 21. The front side of the humidification box 21 is connected to the air supply pipe 3. The oxygen provided by the air supply pipe 3 is humidified by the humidification mechanism 2 and then transported to the user's nasal cavity through the nasal oxygen tube body 1, thereby realizing oxygen delivery to the user. A wet curtain 26 and a water pump 22 for humidifying oxygen are fixed inside the humidifying box 21, a water pipe 23 is fixed on the side of the humidifying box 21, a diversion box 25 for dispersing the water flow is fixed on the humidifying box 21, and the water pipe 23 is used to connect the water pump 22 and the diversion box 25. The water level of distilled water in the humidifying box 21 is higher than the lower surface of the wet curtain 26 to prevent oxygen from directly entering the nasal oxygen tube body 1 without humidification. The water pipe 23 is connected to the water pump 22 and the diversion box 25 respectively.
[0024] Specifically, a drainage plate 27 is fixed to the bottom of the inner wall of the humidification box 21, and the top of the drainage plate 27 is inclined.
[0025] In this implementation plan, please refer to Figure 3 Under the action of the top slope of the guide plate 27, the water flow can automatically gather toward the water pump 22, thereby guiding the water flow.
[0026] Specifically, a ball valve 24 is provided on the surface of the water pipe 23 to control the flow rate of water.
[0027] In this implementation plan, please refer to Figure 3 By controlling the opening of the ball valve 24, the water flow rate can be controlled. By controlling the water flow rate, the humidity of the gauze block 261 can be changed, and the humidity of the oxygen can be further changed to meet different usage requirements.
[0028] Specifically, the wet curtain 26 includes a gauze block 261 and a bottom block 262 fixed inside the humidification box 21, the gauze block 261 is fixed on the bottom block 262, and the water flow can humidify the oxygen passing through after soaking the gauze block 261.
[0029] In this implementation plan, please refer to Figure 3 and Figure 4The water flows onto the gauze block 261 to wet it, and the oxygen flow passes through the gauze block 261 to humidify the oxygen. The bottom block 262 is fixed to the bottom of the gauze block 261, and the two ends of the bottom block 262 are respectively fixedly connected to the two sides of the inner wall of the humidification box 21, thereby realizing the stable installation and fixation of the gauze block 261.
[0030] Specifically, the top of the bottom block 262 is an upward curved surface for guiding water to flow downward.
[0031] In this implementation plan, please refer to Figure 4 After the water flows to the bottom block 262 , it automatically flows downward along the curved surface at the top of the bottom block 262 to prevent the water from accumulating on the bottom block 262 .
[0032] Specifically, the flow diversion box 25 includes a square box 251 fixed on the top of the humidification box 21 and a round hole 252 opened at the bottom of the square box 251. The square box 251 is connected to the water pipe 23, and the round hole 252 is used for dispersing the water flow.
[0033] In this implementation plan, please refer to Figure 3 After the water flows into the square box 251 , it flows downward to the gauze block 261 through the multiple circular holes 252 . The water flow is dispersed through the multiple circular holes 252 , so that the gauze block 261 is evenly soaked.
[0034] Specifically, a transparent viewing window 4 is inlaid on the surface of the humidifying box 21 , and the transparent viewing window 4 is used to mark the water level inside the humidifying box 21 .
[0035] In this implementation plan, please refer to Figure 1 The transparent viewing window 4 is used to mark the water level inside the humidification box 21, so that personnel can observe the water level inside the humidification box 21 from the outside. When the water level is low, distilled water can be added to the humidification box 21 in time.
[0036] The working principle and use process of the utility model are as follows: oxygen enters the humidifying mechanism 2 through the air supply pipe 3, and the oxygen airflow passes through the wet curtain 26. After the gauze block 261 at the wet curtain 26 is soaked with distilled water, the soaked gauze block 261 humidifies the oxygen airflow passing through. The humidified oxygen airflow is then transported to the user's nasal cavity through the nasal oxygen tube body 1 to prevent the nasal airway from drying out and reduce the discomfort during oxygen delivery.
[0037] The water pump 22 is operated to transport the distilled water in the humidifying box 21 to the square box 251 through the water pipe 23, and then disperses the water flow through the multiple circular holes 252, so that the water flow disperses and flows to the gauze block 261, so as to achieve uniform soaking of the gauze block 261. The water flow on the soaked gauze block 261 continues to flow downward along the gauze block 261 to the bottom block 262, and then flows along the bottom block 262 to the bottom position of the inner wall of the humidifying box 21 to achieve the recycling of the distilled water. At the same time, a ball valve 24 is also installed on the water pipe 23. By controlling the opening of the ball valve 24, the flow of water is changed, thereby changing the humidity of the gauze block 261, and further changing the humidity of the oxygen to meet different usage requirements;
[0038] A transparent viewing window 4 is embedded in the humidifying box 21, and the transparent viewing window 4 is used to mark the water level inside the humidifying box 21, so that personnel can observe the height of the water level inside the humidifying box 21 from the outside. When the water level is low, open the cover of the water inlet on the rear side of the humidifying box 21, and then add distilled water to the humidifying box 21. After adding, tighten the cover of the water inlet.
